prompt_setcallback({buf}, {expr}) *prompt_setcallback()*
Set prompt callback for buffer {buf} to {expr}. When {expr}
is an empty string the callback is removed. This has only
effect if {buf} has 'buftype' set to "prompt".
The callback is invoked when pressing Enter. The current
buffer will always be the prompt buffer. A new line for a
prompt is added before invoking the callback, thus the prompt
for which the callback was invoked will be in the last but one
line.
If the callback wants to add text to the buffer, it must
insert it above the last line, since that is where the current
prompt is. This can also be done asynchronously.
The callback is invoked with one argument, which is the text
that was entered at the prompt. This can be an empty string
if the user only typed Enter.
Example: >
call prompt_setcallback(bufnr(''), function('s:TextEntered'))
func s:TextEntered(text)

prompt_setinterrupt({buf}, {expr}) *prompt_setinterrupt()*
Set a callback for buffer {buf} to {expr}. When {expr} is an

{buf} has 'buftype' set to "prompt".
This callback will be invoked when pressing CTRL-C in Insert
mode. Without setting a callback Vim will exit Insert mode,
as in any buffer.
prompt_setprompt({buf}, {text}) *prompt_setprompt()*
Set prompt for buffer {buf} to {text}. You most likely want
{text} to end in a space.

When on MS-Windows, gdb will run in a buffer with 'buftype' set to "prompt".
This works slightly differently:
- The gdb window will be in Insert mode while typing commands. Go to Normal
mode with <Esc>, then you can move around in the buffer, copy/paste, etc.
Go back to editing the gdb command with any command that starts Insert mode,
such as `a` or `i`.
- The program being debugged will run in a separate window. On MS-Windows
this is a new console window. On Unix, if the |+terminal| feature is
available a Terminal window will be opened to run the debugged program in.
